I have 4 battery lifepo4 youth power 4x 100 ah in parallel 48v on an inverter deye 8kw and pv of 6500w system … my question is i am using buss bar i want to know if it s correct, my buss bar is copper 40 cm x2.5 cm and thickness or 0.5 cm i have a 125 amps breaker for the battery even they have...

True i made much fault i learned from them to much thank you bro

Thank you for your help… my problem is i have 2 grids as i said on top of the subject one of the government EDL which is so cheap but it rarely On bc of the crises but their s another grid which is private generators and so expensive like 0.45$ cent for 1kw so im trying to find a solution using...

400 ah 50% is 200 not 100 ah + in that picis only 40 max charge and discharge isn t too low

Should b 400 ah bcz in parallel will be all as one

Thx

Ok thx

Oh i see on that link thx

I am not an electrician i am an auditor i work with bank accounts and balance sheets but i built my own solar system from zero so i am learning just sorry if some questions is too idot for you but i am a level 1 in solar so i see A in charging A in discharging so i wanted to know what is A their...

10 mm or 20 mm copper is better

U can just say … just use buss bar and your battery will be equal

0.5mm x 25 mm and length 400 mm i just check it by the tape

dear fellows , i check the manual and checked video and many explanation and in conclusion or what i got that all made same scenario : if zero export to load / load first / 020 to export to girl and no tick to sell load..... mean pv first to load then battery and if no sufficient power the grid...

I have my my solar system 6500w and my battery size 400 ah im using them for home and my work shop so i might use high current so that s why it s better to purchase another bussbar 20 mmm thickness or i ll buy another 15 mm copper and adding to my available copper

I will tomorrow because we are in different time zone im +3 and its night here so tomorrow i ll post it

Sorry sorry my mistake im confusing between cm and mm ohhh it s the fatigue i use here cm and m in my country so i didn t convert well sorry 2.5cm x 0.5 cm = 25 mm x 5 mm copper sorry again = 125 mm2

I have a big generator 22 kva i am giving the battery charge on generator 2200w 10A and i know my load is only 5-6 amps but my generator not giving the battery once to load once to battery ??‍♂️ i wm so confused

I am asking if their is any programs can calculate you r c rate your charge and everything shut down restart amper ??

I fix it in up their to 0.5 cm so im good to go for 100 amps ch and disch

I am using a 8kw inverter just a new user like 2-3 months any hint how to change time zone? Bcz in my country we have summer time and winter time and my inverter always using summer time +1 hr

Did you try it?

Why not use 6 in series and anothe 6 in series and then combine them ++ and - - and then put them on one mppt it worse with me and if want add more panels can make more panels but in parallel like 7 in series and 7 or 8 in parallel doesn t work?

Thx can you gives me the formula you made thickness x diameter = 5. X. 25. = 125 mm2 How u got ~450 amps result

Dear forum, I do have 8kw inverter deye with : voc of 370Vdc(125Vdc 500Vdc) and mppt 150vdc 425 Vdc and Max isc 28Adc + 28Adc and Max input power 10400 W The question is as long it is 8kw mean 8000w why it mentioned 10.4kw max can i reach that or exceed it? Second which should i choose 425...

Their s a pic in the comments i attached again data sheet

Yeah 49.6 my fault

Isc max is 28 Ad + 28 Ad not mentioned any voltage

Should i go more like 0.50c charge and discharge ? Yeah i am using buss bar and all wires same length and 25 mm thickness with a breaker of 125 a and on each batt has her own breaker but i want to see how much i can max charge and discharge and stay in safe zone

I did but none replied

I am thinking as long we have bms on a lifepo4 lithium battery it gives u voltage by cell temp and many many details can it gives you how many cycle u did or how many time u empty it and refill any idea ? Or any settings in it we can find out?
